Dayco Poly-V Serpentine Belt

The Dayco Poly-V Serpentine Belt is a multi-rib drive belt (also called a serpentine belt, poly-V belt or accessory drive belt). It transfers engine power to accessories such as the alternator, power steering pump, water pump and air conditioning compressor. Dayco is a long-established maker of belts and engine drive components, and this line is built for dependable everyday performance.

Key Features:

• Multi-rib design runs smoothly over pulleys and gives a large contact area for efficient power transfer
• Synthetic rubber construction helps resist heat, oil, ozone and general wear
• Reinforced tensile cords add strength and help the belt hold its length and stay stable under load
• Made for quiet operation with low vibration
• Precision-molded ribs help the belt track and grip evenly in the pulley grooves

A worn, cracked or glazed serpentine belt can cause squealing, slipping and loss of accessory function. Replacing it on schedule helps keep the charging, cooling, steering and climate control systems running reliably. Check the tensioner and idler pulleys when you replace the belt.
